PORTABLE SUCTION CLEANING-MACHINE.

Specification of Letters Patent.

Application filed January '31, 1910. Serial No. 541,094..

To all whom it may concern:

Be it known that we, DAVID P. MOORE and SAMUEL B. PACK, citizens of the United States, residing at Washington, the District of Columbia, have invented certain new and useful Improvements in Portable- Suction Cleaning-Machines, of which the following is aspecification, reference being had therein to the accompanying drawing.

Our present invention relates to improvements in vacuum cleaners and has for its object to produce a portable machine of this character, having the novel features hereinafter described and claimed.

In the accompanying drawings Figure 1 is a side elevation of one form of the complete machine.

Fig. 2 is a top plan View thereof with the hood or dome removed.

Fig. 3 is a side elevation of a machine, the receptacle being shown in section with the dust bag in position therein.

Fig. 4 is a detail view of the air filtering and dust collecting bag, the suction head and the closure for the casing of the machine with which the suction head is associated.

Figs. 5 and 6 are detail views of the means for detachably holding the closure for the open end of thecasing to the receptacle or casing of the machine.

Referring to the drawings 2-- The numeral 1 designates'the casing or receptacle, which is provided with the two forward rollers or casters 2, and with the brackets 3, in which is journaled the shaft 4, carrying the large power wheels 5, preferably at the rear of the casing. Mounted upon this shaft, are the series of eccentric disks 6, upon which are mounted the eccentric straps 7, carrying the rods 8, whose upper ends 9, are connected to the central or rocking member 10, of the double-acting bellows 11. These bellows are carried by the removable lid or cover 12, which is removably fitted over the upwardly projecting flange 13, which forms an exit through which the contents are removed from the casing, the two clamps 16, holding the cover in place.-

These bellows are suitably constructed and supported, being represented, in Fig. 2, as held in place by the clamps 16. They operate in a well known manner to produce substantially continuous vacuum or reduced air pressure within the casing-1, the air beingtaken from the casing to the bellows through valved pipes a, b, c, d and escaping'through the valved apparatus 7.

Patented June 1, 1920.

As these details of bellows construction and air connection form no part of our present invention. they need not be shown or described in detail. I

To cover the bellows and form a box like machine, we employ the removable hood or dome 20, which is held in place by.

' to be cleaned, we employ the coil spring 26.

In order to prevent the suction head from turning and also to prevent it from being shocked by wrinkles in the rug or carpet as the head passes thereover, we employ the two flat springs 27, whichare secured to the casing and have their openings receiving the screws 9 carried by the suction head. To remove the suction head and em- In the machine represented in the draw-' ings'the casing is open at one end, which opening is closed when the machine is in use by a tight fitting, although easily removable,

closure 32. For removing the dust we employ an air-filtering and dust-and-dirt-collecting bag 29, of suitable fabric, which will permit the air to freely pass through .it while retaining the dirt. The open end of this dust-filtering bag is fitted to a frame 33 that holds it distended, this frame fitting the interior of the casing, as represented in Fig. 3, and being removable from the casing, carrying with it the filtering bag, as represented in Fig. 4. The closure 32 is perforated at 31 to receive the elbow 30 of the open end of the casing.

' carry thumb screws 37 that bear against the closure to hold it in place.

The removable closure 32 carries the suc-' tion nozzle of the machine and alsocloses It servesalso to close and hold in place the frame 33 that carries the dust bag and holds the mouth thereof distended. This arrangement is eX- ceedingly advantageous in vacuum cleaners of the portable, manually operated, type,

' in which the suction isrelatively feeble, so

that it becomes of the utmost importance that the length of the conduit between the suction nozzle and the place where it discharges into the dust bag should be as short as possible. The arrangement shown, in which the mouth of the removable dust bag is held distended by a frame that fitsthe end of the casing of the machine, and that frame in turn is closed and-held in place by the closureframe 32, and the suction nozzle is carried or supported directly by the said closure, reduces to a minimum the length of said -a1r condult. Th s arrangement also permlts the employment of a dust bag of a size to practically fill the chamber of the casing into which it is inserted.

'lVhat we claim, as new, 1s:-

7 1'. A portable suction cleaning machine comprising a casing formed with an open end, a removable dust filter bag, adapted to be inserted into and removed bodily from the casing through the said open end, a

and in position to closethe open endthereof andalso to hold the frame for the open end of the dust .bag in place, and means for causing a suction of air through the casing.

2. A portable'suction cleaning machine, comprising a casing open at one end, means for causing a suction of air through the cas- D gagement with the surface belng cleaned, a

frame by which the nozzle is carried arranged to close the open end of the casing practically air tight and separable therefrom, means for securing the nozzle to the casing, an open frame adapted to fit closely the innerwall of the casing near its open end and to be itself closed by the frame that carries the nozzle, and a filter bag secured to the said open frame, the open frame being removable from the casing and carrying with it the filter bag when the nozzlesupporting frame is separated from the casing.

In testimony whereof we afiix our signatures in presence of two witnesses.
